Description

Siuhlungl protruding part of the carrier * as Counterweight for the guide roller 3 specific weight, weight piece 9.

In the embodiment shown in FIG

the weight 9 is arranged in such a position to the carrier 6 that it is attached to the carrier 6

«If the guide roller3 maintains the equilibrium, i.e. that

Weight piece9 is slightly larger for reasons of stability, than would be required for equilibrium.

Next, the carrier 6 is on a second, in Achsnch-

the guide roller further than the first lifting device

device 7, 8 remote from the guide roller 3 point

a second lifting device, i.e. attached to a trolley IO by means of a load rope 11. Im drawn The state when the entire weight of the guide roller 3 is borne by the carrier 6 takes place

Load 8, for example, eighty percent of the weight

tes of the guide roller 3 and the device S, while the remaining twenty percent of the load rope 11

are to be taken over. In the unloaded state of the

Device 5 is the weight of the load ropes 8 and 11 are each worn about halfway.

The in F i g. 1 framing shown 1 of the drying In the known paper machines:> 5 part of a paper machine carries out a large number of removal and reinstallation of felt guide rollers from drying rollers and felt guide rollers, of which so-called roller boards are available in smaller web widths. 1 turns two drying rollers 2 and three guide rollers 3. These roller boards are longer than the felt boards can be seen. A hood of the dryer section is drilled and grazed about halfway in the chair - indicated by its boundary line 4,
inserted. The guide roller to be removed is brought to a device 5 for removing and installing the iodine with the help of pulley blocks on the roller guide rollers 3 to which it is currently being expanded. Then the guide roller on the board attached to the guide roller 3, in the attached state, is pushed in the axial direction out of the frame in the axial direction of the guide roller 3 over the frame 1 until it protrudes in its center of gravity on a carrier 6 protruding. Which can be hung up using the chair lift house crane. By means of 65 ment 1 protruding part of the carrier 6 carries one of the crane, the guide roller is completely dismantled and the receptacle for a lifting device 7, ie is put aside until it is reinstalled. The installation of the trolley of a nacelle crane by means of the guide roller is carried out in the same way. a load rope 8 attached. He continues to ask about them
